I'm a very happy user of GrapheneOS on a Pix4a since about 18 month and so I bought 2 brandnew Pix6 a few days ago. One for my wife and one for me.
Last night I wanted to get GrapheneOS on my 'kinda coral' and thought to do it the Web-install way.
Everything went well, until the "Flash release" step, where it did all it's steps until right at the end, where it displayed an error message on the web-page - which to my utter embarassement,I haven't captured.
On the Pix6 I got the 'fastbootd'-screen, where I selected option 3 'Reboot to bootloader'.
I then got a screen (Pix6) saying "The bootloader is unlocked.... Visit this link on another device: g.co/ABH ..."
After pressing the Power-Button (several times) I got yet another screen saying "Your device is corrupt... Visit... g.co/ABH".
Finally, my Pix6 is pretty warm (even hot) and on the black screen there is 1 gray icon showing a loading battery. No button-push works and I am totally stuck.
If I remember correctly, I did my Pix4a 18 month ago the same way, which worked fine. Although in a different environment for sure. Then Macos, now Ubuntu 20.04.
I would very much appreciate any help - thank you.
